Daughter of missing Vietnam soldier recounts father's classified service and presses for continued accounting

A woman who identified herself as a daughter of a missing service member described her father's service in a unit she called the "Studies and Observation Group," saying the unit's name was chosen to conceal highly classified missions across the border into Laos and Cambodia. She said the family's search continues despite fading witnesses and deteriorating sites.

"Our father, he served in a unit called the studies and observation group," the family member said, and added that "as time continues to pass, hopes for recovery go dimmer" as veterans and physical sites age or are lost. She thanked Rolling Thunder NC5 for the invitation and expressed hope that remaining accounting efforts continue while family members are still living.
